Description

Technical Field

[0001] This utility model relates to the field of detection instrument technology, and in particular to a real-time detection device for aqueous phase density. Background Technology

[0002] As a type of water-in-oil (W / O) latex-based water-resistant industrial explosive, emulsion explosives are highly susceptible to the influence of the density of the aqueous solution on key performance indicators such as detonation velocity and saturation. Therefore, the preparation and monitoring of the aqueous solution are crucial for ensuring the stability and safety of the explosive performance. However, in the current production process of emulsion explosives, the density detection of ammonium nitrate solution still relies on traditional manual testing methods. Specifically, after each batch of aqueous solution is stirred and mixed, the operator manually scoops a sample of the upper layer of solution from the top of the preparation tank and transfers it to a testing container for density measurement.

[0003] First, this manual method of testing the density of the aqueous phase is inefficient and prone to error. It is greatly affected by human factors, such as sampling location and sample size, which can lead to inaccurate and inconsistent measurement results. Second, because the aqueous solution often reaches high temperatures during stirring and mixing, there is a risk of burns to the testing personnel. Furthermore, manual testing methods typically involve intermittent sampling, failing to reflect the dynamic changes in the aqueous phase density in real time. In the production of emulsion explosives, the density of the aqueous solution may change with the addition of raw materials, stirring, and temperature variations. However, manual testing only provides static data at a specific moment, unable to continuously monitor density trends, making it difficult to adjust production parameters in a timely manner to ensure product quality stability. Utility Model Content

[0004] The purpose of this invention is to provide a real-time water phase density detection device to solve one or more technical problems existing in the background art.

[0005] To achieve this objective, the present invention adopts the following technical solution:

The flange is fixed to the top of the aqueous phase preparation tank, and the tuning fork detection component is located at the bottom of the flange, with its detection end extending into the tank. The tuning fork detection component is electrically connected to the input terminal of the data processing module. The data processing module receives the measurement signal from the tuning fork detection component and converts and calculates the measurement signal to obtain aqueous phase density data.

[0007] Preferably, the tuning fork detection component includes a tuning fork structure and a piezoelectric ceramic. The piezoelectric ceramic is disposed on the tuning fork structure and has an excitation end and a feedback end. The excitation end of the piezoelectric ceramic is used to generate an alternating force and transmit it to the tuning fork structure, and the feedback end of the piezoelectric ceramic is used to receive changes in the vibration frequency of the tuning fork structure.

[0008] Preferably, the tuning fork detection component further includes a temperature sensor, which is disposed on the tuning fork structure and is used to monitor the temperature of the liquid being tested.

Through the conversion and calculation of the data processing module, the measurement result of the solution density is fed back to the operator, realizing automatic detection of solution density and improving detection efficiency. Compared with the existing detection methods of manual sampling and visual reading of density meters, the detection device of this invention not only reduces the error caused by human operation and ensures the accuracy and consistency of measurement results, but also eliminates the need for operators to directly contact the high-temperature aqueous phase solution for sampling and measurement, effectively avoiding safety risks such as burns.

Detailed Implementation

[0020] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0021] This embodiment provides a real-time water phase density detection device, as shown in the attached diagram. Figure 1The system includes an aqueous phase preparation tank 1, a stirring assembly 2, and a density detection assembly 3. The stirring assembly 2 is located on top of the aqueous phase preparation tank 1, with its stirring end extending into the aqueous phase preparation tank 1. The density detection assembly 3 includes a flange 31, a tuning fork detection component 32, and a data processing module. The flange 31 is fixed to the top of the aqueous phase preparation tank 1, and the tuning fork detection component 32 is located at the bottom of the flange 31. The detection end of the tuning fork detection component 32 extends into the aqueous phase preparation tank 1. The tuning fork detection component 32 is electrically connected to the input terminal of the data processing module. The data processing module is used to receive the measurement signal from the tuning fork detection component 32 and convert and calculate the measurement signal to obtain the aqueous phase density data.

[0022] By installing a stirring assembly 2 and a density detection assembly 3 on the aqueous phase preparation tank 1, the density of the aqueous solution after stirring and mixing is detected. By directly immersing the tuning fork detection component 32 in the solution, the tuning fork detection component 32 measures the density of the liquid by the change in vibration frequency. The measurement result of the solution density is fed back to the operator through conversion and calculation by the data processing module, which improves the detection efficiency. Compared with the detection methods of manual sampling and visual reading of density meters in the prior art, the detection device of this utility model not only reduces the error caused by human operation and ensures the accuracy and consistency of the measurement results, but also eliminates the need for operators to directly contact the high temperature of the aqueous phase solution for sampling and measurement, effectively avoiding safety risks such as burns.

[0023] The system is equipped with a tuning fork detection component 32 and a stirring component 2. After the stirring component 2 completes the stirring of the aqueous solution, the tuning fork detection component 32 receives the sound wave frequencies reflected by liquid substances of different densities and transmits the measurement signals to the data processing module of the control center in real time via the transmission line. The aqueous density is obtained by comparing the signal with the standard curve of temperature-frequency-concentration, and the detection data is transmitted to the KingSCADA system for digital display and observation in real time, thereby realizing remote monitoring.

[0024] Preferred options are listed in the appendix. Figure 2 and 3 The tuning fork detection component 32 includes a tuning fork structure and a piezoelectric ceramic 33. The piezoelectric ceramic 33 is disposed on the tuning fork structure. The piezoelectric ceramic 33 is provided with an excitation end 331 and a feedback end 332. The excitation end 331 of the piezoelectric ceramic 33 is used to generate an alternating force and transmit it to the tuning fork structure. The feedback end 332 of the piezoelectric ceramic 33 is used to receive changes in the vibration frequency of the tuning fork structure.

[0025] By employing piezoelectric ceramic 33 as both the excitation and feedback element, electrical energy can be converted into mechanical energy and then back into electrical energy. When the excitation end 331 of the piezoelectric ceramic 33 generates an alternating force, it drives the vibration of the tuning fork structure. Meanwhile, the feedback end 332 of the piezoelectric ceramic 33 can precisely capture minute changes in the vibration frequency of the tuning fork structure, thereby achieving accurate measurement of the density of the aqueous solution. By accurately measuring the change in vibration frequency, the density value of the liquid can be calculated, improving the accuracy of the measurement.

[0026] The piezoelectric ceramic 33 is made of inorganic non-metallic materials, while the tuning fork structure is made of stainless steel. Both have excellent high temperature resistance and corrosion resistance, and can maintain stable performance in harsh working environments, ensuring stability and reliability during long-term vibration.

[0027] Preferably, the tuning fork detection component 32 further includes a temperature sensor 34, which is disposed on the tuning fork structure. The output end of the temperature sensor 34 is connected to the data processing module. The temperature sensor 34 is used to monitor the temperature of the liquid being tested in real time and to compensate for changes in the elastic modulus of the tuning fork.

[0028] Preferably, the tuning fork detection assembly further includes an extension rod 35 and a protective sleeve 36. The two ends of the extension rod 35 are connected to the flange 31 and the tuning fork structure, respectively, and the protective sleeve 36 is fitted on the outside of the extension rod 35.

[0029] By setting an extension rod 35 and placing the tuning fork structure at its bottom end, the tuning fork structure extends into a deeper portion of the aqueous phase preparation tank 1, ensuring that the tuning fork structure is immersed in the aqueous solution. A protective sleeve 36 is provided on the outside of the extension rod 35 to protect it, preventing corrosion from the aqueous solution, extending the service life of the tuning fork detection component 32, and reducing maintenance costs.

[0030] Preferably, the tuning fork structure includes a tuning fork arm 371, a balance chamber 372, and a mechanical support 373. The balance chamber 372 is located at the bottom end of the extension rod 35, the mechanical support 373 is located inside the balance chamber 372, the tuning fork arm 371 is located at the bottom of the mechanical support 373, and the piezoelectric ceramic 33 and the temperature sensor 34 are both located on one side of the mechanical support 373.

[0031] By setting up a balance chamber 372 to support the mechanical support 373, the influence of external interference on the tuning fork vibration is reduced, thereby improving the stability of the measurement. The mechanical support 373 is not only used to transmit vibration but also to support the piezoelectric ceramic 33 and the temperature sensor 34.

[0032] Preferably, the tuning fork detection assembly further includes a protective cover 374, which is fitted onto the outside of the tuning fork structure. By providing a protective cover 374 on the outside of the tuning fork structure, the accuracy of the measurement is ensured while avoiding the influence of impurities such as foam generated during the addition of sodium nitrate and stirring of ammonium nitrate on the test results.

[0033] Preferably, the tuning fork detection assembly further includes a meter 38 and a terminal block 39, both of which are located on the top of the flange 31 and are electrically connected to the piezoelectric ceramic 33. The meter 38 allows operators to more directly observe the density value or other relevant parameters of the aqueous solution. The terminal block 39 enables electrical connection between the tuning fork detection component 32 and an external data processing module.

[0034] Preferably, the stirring assembly 2 includes a stirring motor 21, a reducer 22, a stirring shaft 23, and a stirring paddle 24. The stirring motor 21 and the reducer 22 are positioned vertically above the aqueous phase preparation tank 1. The stirring shaft 23 and the stirring paddle 24 are located inside the aqueous phase preparation tank 1. The rotating shaft end of the stirring motor 21 is connected to the input end of the reducer 22, the output end of the reducer 22 is connected to one end of the stirring shaft 23, and the other end of the stirring shaft 23 is connected to the stirring paddle 24. The stirring paddle 24 is located inside the aqueous phase preparation tank 1 and immersed in the aqueous phase solution. The stirring motor 21 drives the stirring shaft 23, thereby rotating the stirring paddle 24 and stirring the aqueous phase solution.
